We are continuing to roll out IP telephony to departments and one of the teaching hospitals will be set-up tomorrow (82 handsets).
We had to do a bit of prep work and change all the switches in the building over to Cisco 3750 POE switches to power the phones. Also setting up the voice VLANs to function across there and a few other 'fiddly' bits we discovered while setting up.
The 'fiddly' bits included the hospital emergency phone number being the start of a range of our numbers which caused a few head scratches, as well as the fact that, as the phones will be on the university network, they will be barred from calling the hospital number.
In the case of the emergency phone, the problem was that if the emergency number was 1111 and we had 5 digit extensions from 11110 through to 11119 then university personnel would be ringing the emergeny number by mistake.
